Back to IUI after IVF

Has anyone had any success with IUI after trying IVF or some other method?

After a natural pregnancy and miscarriage I at 3months. I eventually tried IUI 3 times with clomid, all failures, 1st IVF only one fertilized egg and boom baby that was 3.75 yrs ago, yay. Now 2 subsequent IVFs both failed, no more coverage or $ to try IVF again but IUI still covered and my odds with either were and still are in the 0-5% range. Even with those odds and one success i am still willing to keep trying, it's been over 8 years with 1 successfully attempt, tick tock, now 40 (maybe it's just wishful thinking at this point). I'd be willing to try IVF several more times if it were covered but it's not.
